ASR-5 RADAR DUAL FEEDHORN ANTENNA MODIFICATION. VOLUME II. DESCRIPTION OF FEASIBILITY EFFORT
The report discusses the efforts carried out to determine the feasibility of a dual feedhorn configuration to be employed with the doubly-curved ASR-5 antenna reflector. The feedhorn geometry is modified to provide a tilted up, receive only, second elevation plane pattern in addition to the normal elevation plane pattern of the original design. The intent of this terminal radar antenna modification program is to produce separate antenna two-way coverage patterns for the close-in and long-range capabilities of the radar system. It is intended that the close-in coverage will be obtained by transmission on the normal (low) beam and reception on the second (high) beam. The long-range coverage will be obtained by both transmission and reception on the normal beam. It is expected that the antenna will be tilted down one or more degrees from the typical unmodified ASR-5 design elevation angle.
